Yes it is correct...i just said an example to explain the asked question as in the solar system, sun and Jupiter have its barycentre ouside both the bodies and are vice versa for others.
Yes you are right... The two forces are same and is of the magnitude F=GMm/r^2 . Actually both the object gets dragged to the point of their centre of mass. As given in one example a ball excerts the same force as that of the Earth and both of them gets closer to its Centre of mass under their...
Actually during integration we set two limits t1 and t2 so that we get the displacement between the 2 time interval. After integration we gets the equation of displacement(with respect to time) of a particle . And when we sets the limit we get the displacement during that particular time...
According to Newton every mass attract each other. For me I go with Einstein s theory, mass is a form of energy and it can bend the space time and as a result every object should get attracted to earth. As there is a force pulling the object downwards, a work should be done to escape or move a...
There is no need of making it complex. Actually it is very simple. Imagine an escalator with a hight 'h' and it is constant even if the belt is moving in the opposite direction. Let the velocity of belt be 'u' and velocity of man be 'v'.
The velocity with which the man climbs the escalator is '...
